What is the best way to get to the back 3 plugs on a 3.3L engine?

This is one of the great mysteries of our time. There are two ways to get to the plugs. First, put it on a lift and reach up behind the engine so that you can remove the plugs. The second way is to remove the top end of the engine, phlenum, coil packs and throttle body and reach from over the top. Neither way is easy. You can always try to reach around the sides of the phlenum but it is almost impossible.

Place the van on a set of ramps, under neith you can reach the spark plug closet to the drivers side, 3/8 drive ratchet,3/8 spark plug socket, the center plug can be reached by also using a 3/8 spark plug socket, long ext and very long ratchet. Also the spark plug closet to the passenger side can be reached by removing the top bolts, bracket for the atlernator, push the alt towards the fire wall and remove plug. I found the plugs were less difficult to install when I used some anti seize compound on the plugs and you should replace the plug wires at this stage. Also replace the fuel filter since the van is on ramps

Hey, try this: Remove the windshield wipers, the wiper linkage and motor, and the water trough.

It will come out in two pieces. The top piece is a cover over the wiper linkage and motor and has several screws holding it on. Once you have that off you'll see that the wiper linkage and motor are in a trough that attaches to the fire wall. the trough serves to catch water coming off of the windshield and keeps it out of the engine compartment. Remove the bolts holding the trough and it will come out as one piece with the wiper motor and linkage inside of it. On the bottom of the trough you'll have to disconnect the windshield washer fluid line and the electrical connector for the wiper motor.

Once this is off, remove the air intake plenum and you will have some pretty good room for changing the back 3 plugs.

Pull the motor? Haha.

I have a 92 Dodge Caravan with the 3.3L and all I did was remove the air intake phlenum and it was a piece of cake to get to the back plugs. Took a couple of hours to get it done.

Either way Git-r-done!

Nah! Go from underneath. You don't have to remove anything and it takes 30 minutes. You don't take the chance of twisting off a bolt head or cross threading a bolt in the intake plenum.

I've done this job twice. A shortcut would be nice; however, I agree with Zanders5 and RIP. Go from underneath/move the alternator & replace the plug wires. Anything else seems to be adding unecessary work to the job. If you don't have access to a lift, get a set of ramps. You can get a set of good quality ones at your local auto parts store for $20.00 plus tax. Jack stands work too, but ramps are perfect for this job (the ground clearance is good). NOTE: IMHO, the backside plug closest to the driver, is the hardest one to put the new plug wire on. Make sure it clicks on good (of course do this with all of them). Good luck!
